Felix,
Start casting a plug and spoon with the OH gear and you will soon have enough casting practise... lol
You can not compare 20lb mono with 30lb braid.
Braid will win everytine.
If I could choose...
I would probably load with 60lb JB Hollow and splice in a 10m 100lb JH Hollow "leader" and then a nylon leader of roughly double the length of the rod.
This would give you all the power and line capacity to handle some big fish on the OH gear...
But you need to determine what species and size fish you will be targeting.
If its fish like queen's and spanish mackerel i would go 40lb with 80lb leader in JB Hollow.
The seceret is to have a balanced outfit for what you want to target.
Hope this helps.
Helps quite a lot Gerhard, legend!
Casting metal jigs with it, like Spanyid Raiders and similar. For casting plugs hmmmm...unless it's a stable flying plug like a GT ice cream or pencil popper I wouldn't even think about it and go straight to my trusty spinning reel gear haha! Just doing this to broaden my horizon a bit and have fun. Although I do think for some situations and types of fishing there can be advantages in using overhead gear.
And I want to get good at it of course, otherwise no point. Will try braid next season for sure.
Target species would be Longtail Tuna, Kingfish (yellowtail) and sometimes Spanish Mackerel, so basically 40lb mainline is more than enough except for the larger kingfish that will burry you, but I've got heavy spin gear for them.
Re the Majorcraft KG Evolution series I can attest to them being nice rods, unbeatable value for money. A friend of mine had the HH, but I never casted that one, so can't tell how strong it is. Probably similar to the heavy Yamaga Blue Sniper Shore Jigging Anton?
